' INTERNAL-COMBUSTION ENGINE WITH ROTATING CYTJINDERS.

To all whom it may concern Be it known that I, WILHELM KIELiNG, a subject of the German Emperor, residing at Frankfort-on-the-Main, Germany, have invented new and useful Improvements in Internal-Combustion Engines with Rotating Cylinders, of which the following is a specification.

This invention relates to improvements in internal combustion engines with rotating cylinders and has for its object to prov de an engine that is small, light and effective and that may easily be dismounted or assembled.

With these objects in view my invention consists in an improved construction of the casing, the cylinders, the connecting rod ends, and in the combination and arrangement of parts hereinafter fully described and claimed, reference being had to the accompanying drawings, in which Figure 1 is a longitudinal section through the internal combustion engine, parts being broken away, and parts being shown in elevation. Fig. 2 is a section through the casing. Fig. 3 is a section through a modified form of the casing. Fig. 4: is a section through the contacting parts of two adjacent cylinders, partly broken away. Fig. 5 is a view of Fig. 4 taken from below. Fig. 6 shows the gearing for actuating the camsleeve. Fig. 7 is a section through the outlet valve. Figs. -8, 9, 10 are separate connecting rods in views at right angles to one another. Fig. 11 shows one half of the main connecting rod with bush. Fig. 12 is a section through the bush according to Fig. 11. Fig. 13 represents an elevation of one grou of connecting rod ends united in' the bus of the one half of the main connecting rod. Fig. 14 is a section through the connecting rod ends and shows in a larger scale the arrangement of the connecting rod ends in two groups on the crank pin. Fig. 15 shows the two halves of the main connecting rod secured together.

Specification of Letters Patent.

Application filed August 20, 1912.

mounted in the hollow crank shaft portion 1 and is connected with the casing 2 so that the latter in rotating rotates the cams 5. The ratio of the gears may be 1:2 or 6:7 as suitable.

As shown the casing 2 consists only of two portions 10 and 11 which are connected with one another by bolts 12. Said bolts engage in lateral recesses 13 (Fig. 4) of the cylinders 6 preventing the same from rotating about their axis. For the same purpose the cylinders are provided with flat faces 14 at the contacting edges of their open end. The

cylinders, furthermore, are formed with collars 15 adapted to engage in corresponding grooves in both halves of the casing, as shown in Fig. 2. I

For the purpose of assembling or dismounting the cylinders 6, only the two parts of the casing require to be brought together or taken apart while the gea'rings for actuating the-valves as well as the heads or ends of the connecting rods are not afiiected. To further simplify the mounting of the cylinders the parts 10 and 11 of the casing may carry rings 16 and 17 respectively, and are provided only with recesses 18 for the insertion of the open end of the cylinders loosely engaged in the two-part-casing on which they rest with their collars 15. The rings 16 and 17 are fitted with grooves 19 to extend over the cylinder collars 15 when the rings are connected with one another by the said bolts 12. To remove the cylinders 6 from the casing only the rings 16 and 17 require to be separated, as represented in Fig. 3, without releasing the halves of the casing so that the elements arranged in the same are not to be affected.

The part 10 of the casing carries an annular projection 30 adapted to be engaged by a suitable cover 20 (Fig. 1) inclosing the actuating gear (not shown) for the outlet valves. Said projection is adapted to be connected with the open end of a pointed silencer 21 which is divided by a perforated wall 22 into a closed chamber 23 and a chamber 24 connected with the atmosphere Into the closed chamber 23 extend gases burnt and assisting the rotation of the engine if the pipes are removed in case the engine is acting without the silencer. To enable an easy removal of the pipes 25 they are secured by means of screw caps 28 to the ders by the centrifugal action of the rotation.

As said, the inlet valves are arranged in the pistons and are operated by the spindles 31 inserted into the connecting rods 32 from cams 5 which are driven as explained above. The connecting rods. having ring shaped I ends are connected to the crank pin as hereinafter set forth. If the engine has seven cylinders, as is assumed in the case illustrated, the connecting rods are divided into two groups of three each and a main connecting rod 33, which is divided longitudinally and each half of the same is connected with a bush 34 (Figs. 11 and 12) in which the annular ends of the connecting rods forming one group are concentrically arranged (Fig. 13). The connection between the rod 33 and the bush 34 is enlarged as shown at (Fig.11) and is provided with holes 51 adapte to be engaged by screw bolts 52 (Fig. 15). The opposite end of the main connecting rod, through which the bolt of the piston is fitted, is provided with an enlargement 53 with holes 54 adapted to be engaged by screw bolts 55, as will be seen in Fig. 15. 43 is an annular slot into which the enlarged ends of the other connecting 44 is an annular flange adapted to be engaged by the ball bearings 45 (Fig. 14)

Into the bush 34 the ring 35 of the con-- necting rod 32 (Fig. 8) is first inserted. Into this ring is fitted the ring 36 of the rod 32 (Fig. 9) and into thesame the ring 37 (Fig. 10) of the connecting rod 32. The ring 37 ,is provided with a flange 38 for the insertion of a roller-bearing 39 '(Figs. land 14). The rings 35, and 36 are formed with recesses 40 to permit the crosspieces or webs 41 arranged between the ring 37 and its rod 32 and between the ring 36 and its rod 32 to move therein. To take up the pressure of explosion laterally projecting extensions 42 are provided on each connecting rod 32 which extensions slide in annular grooves 43 inboth bushes (see the connecting rod 32? in Fig. 14). After each group of connecting rod is inserted into a bush 34 both bushes and therewith the halves of the main connecting rod 33 are connected with one another, for instance by means of bolts screwed through the halves of the main connecting rod. The extensions 42 of the connecting rods 32 within one bush thereby engage in the groove 43 of the other bush and vice versa. The bushes also carry an annular extension 44 for ball bearings 45.
